Hot rolling refers to the process in which the steel is rolled above the recrystallization temperature. After cooling at room temperature, the steel is normalized and cooled to become a hot rolled alloy steel wire rod product. If the application is not strict on diameter tolerance and surface finish, the cost of alloy steel coils is lower than that of cold finished bars. Our hot rolled alloy steel products provide the necessary strength and durability for demanding industrial environments. hot rolled steel square bar are ideal materials for many forging and machining applications, such as in fasteners, bolts, connecting rods, hydraulics, fittings, gear blanks, shafts, hubs, pistons, etc.

In essence, cold drawn stainless steel can be regarded as hot rolled steel that has undergone further processing. The hot rolled steel is further processed in cold reduction mills, where the hot rolled steel gets cooled down at room temperature, followed by a series of annealing and/or tempers rolling. Compared with their hot rolled counterparts, cold drawn steel bars products are able to provide a superior surface finish and are also better in terms of tolerance, concentricity, as well as straightness. As the cold rolled steel supplier, Cumic Steel (professional steel supplier) is engaged in high quality cold rolled steel with competitive price. We provide cold rolled steel china.

Cold rolled steel products have good performance, i.e. through cold rolling, you can get cold rolled strip and steel plate with thinner thickness and higher precision, high straightness, high surface finish, clean and bright surface of cold drawn stainless steel bar, easy to carry out coating processing, many varieties, wide application, and also has the characteristics of high stamping performance and no aging, low yield point, so cold drawn steel bar tolerances has a wide range of applications, mainly used in automotive, printing barrel, construction, building materials. It is also the best material for the production of organic coated steel. Our inventory includes high-grade China cold rolled steel sheet in coil to meet diverse industrial manufacturing standards.

Details of Cold Rolled Sheet

“

drawn steel bar is a product made from hot rolled coil and rolled at room temperature below recrystallization temperature. It is mostly used in automobile manufacturing, electrical products, etc. Cold rolled is rolled at recrystallization temperature, but it is generally understood to be rolled using room temperature rolled material.

Because it is not annealed, its hardness is very high (HRB > 90) and its mechanical processing performance is extremely poor, and it can only be processed by simple directional bending of less than 90 degrees (perpendicular to the coiling direction).

Cumic Steel provides high quality cold drawn flat bar for sale with a reasonable cold rolled sheet price.

Application of Cold Rolled Sheet

“

Cold rolled sheet is used in a wide range of applications, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instrumentation, food cans, etc. Cold rolled thin steel sheet is the abbreviation of cold rolled sheet of ordinary carbon structural steel, also known as cold rolled sheet, commonly known as cold plate, which is sometimes misspelled as cold-rolled sheet. Cold plate is made from hot-rolled steel strip of ordinary carbon structural steel, which is further cold-rolled to a thickness of less than 4mm. Since it is rolled at room temperature without producing iron oxide, the cold plate has good surface quality and high dimensional accuracy, and with the annealing treatment, its mechanical properties and process properties are better than those of hot rolled thin steel plates, and it has been gradually used to replace hot rolled thin steel plates in many fields, especially in the field of home appliance manufacturing.

Production Process of Cold Rolled Steel Sheet Metal

“

Since the production process is not heated, there are no defects such as pitting and iron oxide that often occur in hot-rolled, and the surface quality is good and the finish is high. Moreover, the dimensional accuracy of cold rolled products is high, and the performance and organization of the products can meet some special requirements, such as electromagnetic performance, deep punching performance, etc.

Specification: Minimum thickness is 0.2-4mm, width is 600-2,000mm, length of steel plate is 1,200-6,000mm.

Grades: Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B); SPCC, SPCD, SPCE, ST12-15; DC01-06

Performance: Mainly low carbon steel grades are used, requiring good cold-forming and welding properties, as well as certain stamping properties.

Hot-rolling refers to a metalworking process in which the steel is rolled at above recrystallization temperature (usually exceeds 1000℉). Being heated past its recrystallization point, the steel can be properly formed, shaped, and produced in larger quantities. After being cooled at room temperature, the steel is normalized and cooled off, becoming a finished hot rolled steel product. China hot rolled steel for sale not only has excellent strength and versatility but also is a cost-effective material than comparing with cold rolled steel.

As one of the excellent hot rolled steel sheet manufacturers in China, Cumic Steel (professional hot rolled steel plate manufacturers) produces different types of hot rolled steel with competitive price to meet the demands of clients.

Types of Hot Rolled Carbon Steel

Hot Rolled Carbon Steel Overview

china hot rolled steel plate are widely used in many specialized mechanical equipment and large structural components in the manufacturing industry, for example, in the engineering, energy and mining machinery industries, where many products use steel plateswith thicknesses of 6-20mm. Some of these hot rolled carbon steel plates are flat sheets without hollow cores, while most are 30% porosity plates. Their specifications and sizes vary depending on the product and application. These china carbon steel sheet are cut by plasma or oxygen, which will leave different degrees of flying edges, slag and burrs on the cut surface. These must be removed, otherwise the aesthetics and usability of the finished product will be affected.

Different Usage of Types of china hot rolled steel sheet Products

“

1. Steel for structure

It is mainly used in the production of steel structural parts, bridges, ships and vehicles.

2. Weathering steel

With adding special elements (P, Cu, C, etc.), weathering steel has good corrosion resistance and atmospheric corrosion resistance, and is used for the production of containers and special vehicles, and also for building structures.

3. Steel for automobile structure

It has high strength china steel strip with good stamping performance and welding performance, used for the production of frame, wheel, etc.

Welding Notice of Hot Rolled Carbon Steel Flat Product

“

Due to the good welding performance of hot rolled carbon steel flat product, in the condition of not thick plate, and the welding requirements are not too high, the choice of AC spot welder can achieve the welding requirements.

If the cost of equipment allows, try to use medium frequency inverter spot welder to spot weld mil steel plate. The welding effect is better, and the fusion nucleus and welded joints will be more perfect.

There are cold-rolled steel plates and hot-rolled steel plates. Cold-rolled steel plates do not need special cleaning before welding, while hot-rolled steel plates must be cleared of oxidation, rust, oil and other impurities on the surface.

If the capacity of the spot welder used allows, it is suggested that hard specification welding to reduce the effect of heat diffusion on the product, and also to reduce product distortion.

Hot Rolled Steel Products VS Cold Rolled Steel Products

“

Cold rolled steel products are hard, relatively difficult to process, but not easy to deformation, higher strength.

Hot rolled steel products strength is relatively low, and the surface quality is poor (oxidation/low finish), but it has good plasticity, generally for the thick plate. Cold rolled steel products have high strength, high hardness, high surface finish, generally for the thin plate, which can be used as a stamping plate.

The mechanical properties of hot rolled steel products are far from cold rolled steel product, but hot rolled steel products have good toughness and ductility.

Cold rolled steel products due to a certain degree of hardening, low toughness, but can achieve a better yield to strength ratio, used to cold bending spring and other parts, while the yield point is closer to the tensile strength, so the use of the process of danger is not foreseeable, in the load exceeds the allowable load is prone to accidents.
